virtualized radio access network (vRAN)
A Virtualized Radio Access Network (vRAN) is a transformative approach in telecommunications that applies virtualization principles to the Radio Access Network (RAN) components. This innovation allows telecommunications operators to run baseband functions as software rather than on specialized, proprietary hardware. By leveraging standard servers, vRAN facilitates a shift from hardware-centric to software-centric network operations, aligning with the broader network function virtualization (NFV) efforts[1][2].
The primary advantages of vRAN include:
- Reduced Hardware Dependency: It operates on commercial off-the-shelf (COTS) servers, minimizing the need for specialized hardware[1][2].
- Increased Flexibility and Scalability: Networks can dynamically adjust resources to meet changing demands, enhancing overall network agility[1][2].
- Cost Efficiency: By utilizing less expensive hardware and improving network management efficiency, operators can achieve significant total cost of ownership (TCO) savings. ACG Research estimates a TCO savings of 44% for network operators who virtualize the entire RAN[1].
- Enhanced Network Performance: vRAN supports the high performance requirements of 5G networks, including improved connectivity, efficiency, and security. It allows for remote updates and upgrades, facilitating rapid adaptation to new technologies and standards[2].
vRAN is closely associated with 5G networks due to its ability to meet the demands for greater visibility, automation, and adaptability that traditional hardware-based RANs cannot provide. This is crucial for supporting the vast array of 5G use cases, including the Internet of Things (IoT), where the number of connected devices and the volume of data transmission are exponentially increasing[2].
